have a S75348KG5 fridge freezer. There is a considerable amount of water leaking at the bottom of the fridge (by the side of the salad tray) and then onto the floor. I have made sure nothing is touching the back of the fridge. I've also consulted the manual but as there is no diagram indicating the various parts it is of limited use. Could you provide me with a diagram of the workings of this model. Many thanks Suzanne
